Specification of letters Patent, Patented Nov, 14, 1916 Application filed January 15,1909. Serial No. 472,499.

To all whom it may concern Be it known that-I, CHARLES P. WETMonn, a citizen of the; United'States, residing at Milwaukee, county of Milwaukee, and State of Visconsin, have i-n'ventednew and useful Improvements in Computing Machines, of which the following-is a specification.

a My invention relates to improvements in computing machines.

The object of my invention is to provide means whereby all adjustments of the accumulating and printing-wheels will be accomplished by direct transmiwion of motion from a main source ofp ower supply, herein termed the motor and illustrated as a power storing spring thereby avoiding the use of any subordinate5poW'er storing devices and dispensing with all independent reactionary movements of the characterproduced by such devices and inthe absence of breakage precluding the possibility of error in the operation of the machine.

The term registering Eadjustments, as herein employed,refers to all the mechanical movements, except the set-ting movements of the manually actuated keys, the power storinn" movements of the main actuatinglever and its connections, and the printing movements of theprintinp wheels or members after theyhave been adjusted in accordance with the value representedby the set keys. 1

My invention also has for its object the avoidance of retractive springs or other independently acting devices foroperating the connections directlyactedupon by thevalue setting keys, the keys alone being independently retracted to normal-positionby means of separate springer. 4 I

In the following descriptiomreference is had to the accompanying drawings, in which Figaire 1 is a plan view of my invention with it portion of the upper wallof thecasing partially broken away. Fig. 2 is a de tail plan view of part ofthe key-board port-1,5,;

Fig. 26 is a detail side View the locking pawl 158 in its relat-ionto the shaft disk. Fig. 27 is a detail side view of the cam for locking and unlocking the pawl. Fig. 28 is a detail view in vertical section through the end portions of shafts 150 and 136. Figs. 29, 30, 31, and 32 are side viewsof the cams upon the shaft 202, shown in Fig. 25, illustrating respectively the cam for actuating the platen and ribbon feed mechanisms, the cam for actuating the tabulating mechanism, the cam for actuating the type wheel cage for the printing stroke, and the cam for locking the type wheels during the printing stroke. Figs. 33 and 34 a 'e similar views of the main actuator cam and auxiliary actuator cam, located on the shaft 150, shown in Fig. 25. Figs. 35 to 54 inclusive, are side and vertical sectional views drawn transversely through the shaft 200 showing the various grooves of the shifting cams on said shaft which control the variable motion elbow cranks, the several views being drawn to planes completely exposing the respective grooves, with Figs.

35 to 39 inclusive showing the grooves in operation during normal key printing; Figs. 40 to 4.4 showing the grooves in operation when printing totals; Figs. to 49 showing the grooves in operation when printing sub-totals; and Figs. 50 to 54 showing the grooves in operation when printing without adding. All the illustrations on this sheet are viewed from the ri ht hand side of the machine (i. e. from the its hand side of Fig. 25) Fig. 55 is a central vertical section-a1 view of the master cam viewed from the same direction as Figs. 35 to 54. Fig. 56 is a development of the peripheral surface of the central portion of this cam between line -6 7 4 of Fig. 25. Figs. 57,58, 59, and 60 are developments, drawn to cylindrical sections of the central portion of said cam coincident with the eccentric key ways in operation, when printing totals, when printing Subtotals, and when printing without adding, respectively, the master key being shown at starting point in each view.

II. The means for automatically regulating the transmission of motion in proportion to the set values, controlled primarily through a. main differential lever.

III. The means for imparting transmission movements derived from the main actuating lever and exerted indirectly through a power sprin and a series of cams actuated thereby.

IV. The means for dividing the power stored in the niain or power spring, comprising the automatic development and transmission of all accumulating and registering movements from a series of cams driven by said sprin V. The means for transferring or carrying values from an accumulating wheel to the wheel of next higher value.

VI. The means for carrying the cam actuated operations in accordance with the duty to be performed, the different operations being controlled by special keys act ing through a master key.

VII. The means for subdividing the work comprising specializing mechanism controlled through setting keys or push buttons, whereby certain portions of the apparatus may be rendered operative or inoperative at will.
